CLIMATE RISK DETECTION AND PRIORITIZATION OF SUBWATERSHEDS OF THE AGRANI RIVER BASIN USING FUZZY-ANALYTICAL HIERARCHY PROCESSES Authors: Anil SS* & Das SA
ABSTRACT
Drylands are significantly affected by climate change through changing spatial- temporal distribution
of the climatic variables thus making these areas prone to the climate risk. Climatic risk adaptation is
essential through various resource management activities, appropriate policymaking, capacitybuilding institutions, and individuals. This can be achieved by prioritizing areas for climatic risk
adaptation and mitigation. The comprehensive study and inclusion of various climatic variables in
watershed management increase the success of conservation practices and management. Therefore,
with climate risk, there are new challenges to ensure that watershed management also leads to climate
risk adaptation and mitigation.
The current study offers the Fuzzy Analytical Hierarchical Process as an effective multicriteria
decision support model (MCDSM) for identifying and prioritizing the Agrani River's Climate-Risk
sub-watersheds. The methodology was created by combining the Fuzzy-AHP method, basin climate
risk analysis, and a Geographic Information System (GIS). The final score produced from the FuzzyAHP procedure was used to assign ranks to all sub-watersheds. For the Climate Change Mitigation &
Management, these sub-watersheds were prioritized into five categories based on Fuzzy-AHP scores:very low, low, medium, high, and very high.
The result illustrates the nine sub-watersheds covering approximately 35% of the watershed area
prone to climate risk thus given high to very high priority and 15.47 % area has shown moderate
climate risk.
This study suggests that the fuzzy-AHP model, Climate-Risk Analysis, and GIS technique may be
utilized effectively to identify and prioritize critical sub-watersheds for climate change mitigation and
management.
